一道本不卡免费高清 INTRINSIC PROPERTIES OF GRAPHSEMBEDDED IN 3 ERICA FLAPAN, Editor in Chief of the Notices ofthe American Mathematical Society Knot theory is the study of embeddingsof simple closed curves in 3 . A naturalextension of knot theory is the study of embeddings of graphs in 3 . However, incontrast with knots, the structure of a graph can be complex, and this can affectall of its embeddings. If every embedding of a graph has a particular property,then we say that property is intrinsic to the graph. For example, a graph is said to be intrinsically knotted if every embedding of the graph in 3 contains a knot.In this talk I will introduce intrinsic knotting and other intrinsic propertiesof graphs, and present some open problems in the area.

Aaron Brown, University of Chicago Recent progress in the Zimmer program Abstract:The Zimmer program refers to a number of questions and conjecturesabout actions of certain discrete groups, namely, lattices in higher-ranksimple Lie groups. The primary example example of a such a group is SL(n,R). In the past few years, there has been significant progress in the Zimmerprogram. In my talk, I will discuss a recent proof of Zimmer's conjecturewhich shows that (cocompact and certain non-uniform) higher-rank lattices donot act on manifolds with low dimension. I will also discuss recentresults and work in progress that classify all possible non-trivial actionsunder certain dynamical or dimension assumptions.

一道本不卡免费高清 Wesleyan's Undergrad Math Club Presents: The Math of Gerrymandering Abstract:In Gill v. Whitford , a Wisconsin court struckdown the state assembly map as unconstitutional gerrymandering. Will theUS Supreme court uphold this landmark ruling? The plaintiffs case hingeson elementary mathematics, including a simple new efficiency gap formula thatattempts to measure gerrymandering. For deciding whether this formulaworks, a few highly relevant mathematical facts were discovered so recently,the Supreme Court probably doesnt know about them. But you will if you attendthis talk. No math or political science background will be assumed.

Wesleyan's Undergrad Math Club Presents: Ann Guo Career Engineering 101 Come learn how todesign, build, and test careers that will fulfill your passions whileconsidering the limitations imposed by parents, society, andstudentloans. Ann is an MIT-trained computer scientist who eventuallyfound her calling as a career coach. In between, she ran global campusrecruiting at analgorithmic trading firm where she gained insiderknowledge on the hiring process. At Passion Analytics, she is developing anautomated online careercoach to help people at scale. Ann holds BS& MEng degrees in Computer Science from MIT and PhD from UMassAmherst. Lunch will be served!
